GREEN COVE SPRINGS, Fla. -

A former pro wrestler suspected of sexual assault on a child in Colorado turned himself in at the Clay County Sheriff's Office just after noon Wednesday.

In March, investigators with the Mesa County Sheriff's Office obtained an warrant for 56-year-old Stephen Nathaniel Ketcher.

According to the MCSO, Ketcher was spotted in a casino in Orange Park in late March. Deputies obtained a photo (picture on the right) of Ketcher confirming he was in the area.

Clay County authorities say Ketcher walked into the lobby of the Sheriff's Office at 12:15 p.m. and told the receptionist he was wanted on a warrant.

He was to be processed into the Clay County Jail and held pending extradition to Colorado on seven counts of sexual assault of a child.

Ketcher was known to have experience as an over-the-road truck driver, primarily driving between Denver and Ohio in the past. Investigators said he left Colorado in February and hasn't returned.

Ketcher abandoned his last semi-truck earlier this year and was believed to be driving a 1995 white Ford Aerostar, with Colorado plates.

He is known to have numerous ties to Salt Lake City, Utah, where he spent time in the Department of Corrections for an aggravated assault conviction, according to MCSO.

He is also known to have ties around Jacksonville, where his family lives.

Ketcher is a former professional wrestler, known as Steve "Gatorwolf" Ketcher and was a Western Region Heavyweight World Champion in the 1990s. He is still involved with wrestling camps and promotions.
